QUESTION
I have a rabbitmq cluster with 3 nodes. One node has a durable and non-mirrored classic queue named test-queue.
I have a spring boot app using spring-AMQP default connection factory new CachingConnectionFactory() to firstly ensure the queue exists and then subscribe its messages. Everything works fine
Then I started a rolling update to the rabbitmq cluster, where node was being restarted one by one.
I observed following during this process from the log:
Upon start I saw below output

https://docs.spring.io/spring-amqp/docs/current/reference/html/#declarationRetries
The number of retry attempts when passive queue declaration fails. Passive queue declaration occurs when the consumer starts or, when consuming from multiple queues, when not all queues were available during initialization. When none of the configured queues can be passively declared (for any reason) after the retries are exhausted, the container behavior is controlled by the 'missingQueuesFatal` property, described earlier.
and
https://docs.spring.io/spring-amqp/docs/current/reference/html/#failedDeclarationRetryInterval
The interval between passive queue declaration retry attempts. Passive queue declaration occurs when the consumer starts or, when consuming from multiple queues, when not all queues were available during initialization.
You can increase one or both of these from their defaults (3 and 5000 respectively).

I've got two EC2 instances running Artemis in the master-slave replication setup and I always perform rolling upgrade by shutting down the slave, upgrading it and starting it again. Then I do the same with the master. This no longer works for me while upgrading from 2.17 to 2.18. After upgrading one of the nodes I always get this message on that node:
...ANSWER
Answered 2022-Apr-07 at 14:42This bug was introduced via ARTEMIS-3340. It should be fixed in the next release (i.e. 2.22.0). Until then there's no work-around unfortunately.
You may consider creating a completely separate new live/backup pair and then using a DNS update to direct clients from the old pair to the new pair.
QUESTION
We are building an app based on Red Hat JBoss AMQ 6. We wrap some Java code around the base image to provide extra functionalities which are lacking in AMQ 6.
Now, when the CVE of Log4j stroke, we found that this component is vulnerable because it uses log4j 1.x. Now I don't just mean our Java code uses it, but also the base image of Red Hat AMQ 6 uses it. As AMQ 6 is EOL now, Red Hat does not provide support anymore, so there will not be official releases with fix.
So, how do I remove vulnerable log4j 1.x classes from:
- my Java code
- the base image
?
I am building with jib maven plugin.
It seems mvn dependency:tree only gives info about our Java wrapper code, not about the base image. And I don't understand what does the "+" and "-" mean while it gives output like this:

When I run my mocha tests in debug mode, Node.js debugger has a default value used as the --inspect-brk= value.
Without specifying it in the script, my test script looks like that
ANSWER
Answered 2022-Mar-15 at 14:24Remove your debug configurations from intellij using the "-" button. Or just run you application in "run mode", not using the "run debug" mode from the IDE.
How to choose the debug port number57629 is just the default port number for debug configured by intellij.
To change it, open intellij and go to Run | Edit Configurations | Add New Configuration | Attach to Node.js/Chrome
Then, change the Port field value.

QUESTION
I am using Jib to pull a base image, add my wrapper java code to it, and build my image on top of that. Due to the widely known log4j CVE in December 2021, we are looking for a way to remove the vulnerable classes. (Now more CVEs are found in 2022, one of them has a score of 10.0, the highest possible. See https://www.cvedetails.com/vulnerability-list/vendor_id-45/product_id-37215/Apache-Log4j.html)
The base image is near EOL, so the provider answered that they would not release a new version; besides, log4j 1.x also reached EOL long before. But the current situation is that we have no plan of upgrading the base image to next version, so removing the classes seem to be the only way now.
The base image will use /opt/amq/bin/launch.sh as entrypoint. And I have found that I can use customized entrypoint to run a script before that, which removes the classes. Like /opt/amq/bin/my_script.sh, and in that I have run_fix.sh && /opt/amq/bin/launch.sh.
Then I realized that even this would work by mitigating the risk when the application is actually running, the vulnerability scan(part of security process) will still raise alarms while examining the image binary, as this is a static process done before the image is uploaded to the docker registry for production, way before actually running it. They can only be removed at the moment when the application runs, aka at runtime.
Can jib pre-process the base image while doing Maven build(mvn clean install -Pdocker-build) instead of only allowing it at runtime? According to what I have read, I understand it's a big NO, and there's no plugin for it yet.
ANSWER
Answered 2022-Feb-25 at 16:45By the design of container images, it is impossible for anyone or any tool to physically remove files from an already existing container image. Images are immutable. The best you can try is "mark deletion" with some special "whiteout" file (.wh.xyz), which a container runtime will hide the target files at runtime.
However, I am not sure if your vulnerability scanner will take the effect of whiteout files into account during scanning. Hopefully it does. If it doesn't, the only option I can think of is to re-create your own base image.
Take a look at this Stack Overflow answer for more details.

QUESTION
I am just trying to post incoming payload to rabbitmq by using messageStore in WSO2 EI 6.6.0.
API-Code:
...ANSWER
Answered 2022-Jan-05 at 12:35If you want to send, just JSON message as payload to RabbitMQ, don't use message store. Message stores, are storing all synapse message context with payload for later processing - that is their purpose. So that is why you see in decoded RabbitMQ Payload not only the message, but also additional properties.
For sending JSON to RabbitMQ you can use just to a proper endpoint.
Look as this documentation sample.
I have also have made some sequance template for more easy use of sending messages to rabitmq, so next you can may look at this helpful post, and adapt to your own needs.
